  • Patent number: 8808791
    Abstract: A method is provided which includes forming a metal layer and converting at least a portion of the metal layer to a hydrated metal oxide layer. Another method is provided which includes selectively depositing a dielectric layer upon another dielectric layer and selectively depositing a metal layer adjacent to the dielectric layer. Consequently, a microelectronic topography is formed which includes a metal feature and an adjacent dielectric portion comprising lower and upper layers of hydrophilic and hydrophobic material, respectively. A topography including a metal feature having a single layer with at least four elements lining a lower surface and sidewalls of the metal feature is also provided herein. The fluid/s used to form such a single layer may be analyzed by test equipment configured to measure the concentration of all four elements. In some cases, the composition of the fluid/s may be adjusted based upon the analysis.

  • Publication number: 20140193585
    Abstract: A method for modifying the probe tip of a microscope, including the following steps of providing a substrate, providing a metal precursor solution with fluoride ion on the substrate, using the probe tip to dip into the metal precursor solution with fluoride ion on the substrate in order to form a nano-metal particle on the probe tip by the reduction reaction of at least one metal ion in the metal precursor solution. As the result, the probe tip having the nano-metal particle thereon can increase the spatial-resolution of the measuring performance of the field sensitive scanning probe microscope due to the great reduction of stray field effects.

  • Publication number: 20140140647
    Abstract: A high strength, low friction engineered material includes a low friction material filling interstices of a metal microlattice. The metal typically comprises 5 volume % to 25 volume % and the interstices typically comprise 75 volume % to 95 volume %, based on the total volume of the metal microlattice and the interstices. The low friction material preferably fills 100 volume % of the interstices. The metal microlattice can be formed of a single layer, or multiple layers, for example layers of nickel, copper, and tin. The low friction material is typically a polymer, such as polytetrafluoroethylene (PTFE), polyamide (PAI), polyetheretherketone (PEEK), polyethylene (PE), or polyoxymethylene (POM). The low friction material can also include additive particles to modify the material properties. The engineered material can be used in various automotive applications, for example as a bearing, or non-automotive applications.
